Answer: Raul is 15
Step-by-step explanation:
Start of the great depression: 1929
The first presidential election of Richard Nixon: 1969
Difference: 40 years + 6 years= 46 years
46 years/3= 15.3
<span>10p+5=18p-6/2
10p + 5 = 18p -3
10p - 18 p = -3 -5
-8p = -8
p = -8/-8
p =1</span>
To find out how many times, divide 4 by 1/4.
4 ÷ 1/4
4 × 4/1
= 16
Answer:
<h2>18 hours</h2>
Step-by-step explanation:
This problem is on Combined work rate
Step one:
given data
let the secretary take x hours to finish one job
so the clerical worker will take 2x hours to finish one job.
Both of them working together will take 6 hours
Step two:
The combined work formula is
T/A+T/B=1
Where T= time working together
A= time the Clerical worker spent alone
B= time the secretary spent alone
substituting we have
6/2x+6/x=1
solve for x
6+12/2x=1
18/2x=1
9/x=1
cross multiply
x=9 hours
the clerical worker take 2x hours
2*9= 18 hours
